Abstract

The present invention provides an antiknok grade-raising fluxing agent. It is made up by using toluene, methyltertbulyl ether and methylcyclopentadiene-tricarbonyl manganese according to a certain proportion through a certain preparation process. It can effectively raise octane value of gasoline and grade of gasoline, can reduce gasoline knock property and has good combustion property. The utilization of said invention can change the No.60 light-gravity oil into No.90, No.93 and No.95 environment-protecting gasoline, at the same time it also can be used as fluxing agent between methyl alcohol, ethyl alcohol and gasoline to raise combustion heat value of methyl alcohol and ethyl alochol, after said fluxing agent is added into the gasoline, the methyl alcohol and ethyl alcohol also can be added, and can be substituted for partial gasoline, its substituted rate can be up to 19%.

Description

technical field [0001] The invention provides an additive for gasoline for automobiles, in particular to an antiknock-increasing fusion agent. Background technique [0002] The octane number of gasoline is an important indicator that affects the stable combustion of automobiles, improves power and prolongs the service life of engines. In modern technology, in addition to using advanced refining processes (such as catalysis, cracking, reforming, hydrogenation, etc.) to produce high-octane gasoline, it is also used to add tetraethyl lead and tetramethyl lead to gasoline with low octane The method increases the octane number, and the gasoline produced by this method is leaded gasoline. Because the exhaust gas produced after the combustion of this gasoline contains the toxic component of lead, the use of leaded gasoline is banned in countries all over the world. In the prior art, there are also people who increase the octane number of gasoline by adding u...
